CRCS-2150-AX - Cartridge Rotary Single Seal for Axial Movement with Flush/Vent Port and 4-bolt gland fastening with integral vortex breakers
The CRCS-2150-AX is a multi-spring, hydraulically balanced single cartridge stationary seal that is specifically designed to accommodate axial shaft thermal growth/movement, as experienced by one seal on a double ended pump.
The seal is offered with flush (Plan 11 / 13 / 32) port and a gland plate with integral vortex breakers, ideal for slurry applications to prevent gland errosion and wear. The seal also has secondary O-RING seals, complete with a 4-bolt gland fastening.
The rotary cartridge seal has Shrink Fitted seal faces is designed for use with parallel rotating equipment shafts.
The design has a number of innovative design features and comes with Multi-Springs for even face loading and a four stud/bolt gland fastening. The cartridge seal is Set Screw Driven with the gland incorporating a Flush connection which can also be used for Venting the seal chamber.
The seal has a number of design features and comes factory assembled and tested.
Design Features:
- Accomodates +/-1.5mm (+/-0.060") axial shaft movement due to thermal growth.
- Rotary seal.
- Large 3/8" NPT port connection
- Cartridge seal design for ease of installation. Seal faces are pre-set so, unlike component seals, there is no change of operator setting face load incorrectly
- Comes Flush/Vent Connection as standard
- Available in a large range of seal face materials to suit all applications.
Common Applications:
CRCS-2150-AX are suited for Double-ended process pumps, also known as double-suction pumps which are widely used in industries that require high flow rates and reliable fluid transfer. These pumps are designed with an impeller that allows fluid to enter from both sides, improving efficiency and reducing axial thrust.

Safe Operating Limits:
This seal incorporates best practice features and innovation as detailed in our technical blogs and white papers.
** Apply "industry standard" Pressure, Speed and Temperature de-rating factors, by shaft size and application. The safe seal performance characteristics are typical characteristics for each variable in isolation. The individual upper limit values of each variable should NOT be used in multiple combinations of Speed, Pressure and Temperature. Contact our Technical Sales Department for further details.
